sroKE-T'URNING ILATHE.

Application-Emea voctober 4, 1.921. serial no. 50532481 rIhis invention relates toimprovements in spoke turning lathes,` it beingin the nature ture of Patent No. 1,252,271, issued Januaryfl, 19718, tothe HayeslWheelCompany as assignee of lVilliam Kistler and Arthur The objects of the invention are, n,

,First, to providein ar spoke lathe ofxthis operation will definitelyappear from the'.

, rolls 8, servesasv a reference whilev thel spoke detailed `description to follow.

The objects of the invention are accomplished bythe devices andlnie'ans'described in the vfollowing specification. The invenfi tion is clearly dened and pointed out in the claims. A structure constituting-apre! ferred embodiment of the invention isi clear-` ly illustrated 1n the accompanymgv'drawlng, part` of-ithis specification, ing

forming. awhich Fig. I is a perspective View showing an complete 'spoke turning lathe with the in vention incorporated.

Fig. II is a plan view of the lathe, the cover portion, magaziney and unnecessary details being omitted.

Fig. III is a detail elevationview from the front of Figs. I and II.

Fig'. IV vis an enlarged detail sectional view taken on line Qi-4 of Figs. II and III, looking in the direction of the little arrows.

In the drawings similar numerals of reference refer to similar parts throughout the several` views.

Considering the numbered parts of the drawings by the numbers. l is the frame of the machine provided with a bed member 2 which is mounted to oscillate onA the ways 3 supported by the said frame. The same is pivoted in the manner described in the said FatentNo. 1,252,271, and is adjustable as there indicated.

The headstock i is carried Iby the saidV bed plate and driven by suitable gearing 5 and is revoluble and provided With a series of revolving lathe head spindles 6 which have chucks i', each comprising a pair of transversely disposed rollers 84 forreceiving the-mitered vend of a spoke 9. `The tail stock l0. also revolves and isi provided with a series of non-revoluble vspindles l'lof the desiofn appearing inthe said' yformer patent,-

and operating in vthe same way by the same cam means. 1

vided with a seriesof straight blades lll' and curvediblades'l of the right contour to-turn they hub end of the spoke, forming the enlarged head at that point.

i It will, be observedv that the tapered end 9 of the spok'e,being engaged by the clutch is being" turned by the cutter hea-d.

- ,0n the bed inem-ber 2 is vdisposed a cut-ter means.comprising the rotary cutter 16I carried onV suitable bearings` 17,118, and disposed toY out an annular groove 19 -inwth'ey spoke, thereby forming the tenen thereof. This .cutter is driven byshaft 20l supported4 cutter.

`any source of power, kwhich may be a pulley 25 on the cutter'head shaft of the machine.y

he cutter head l2 is of a;usual design, carried. on shaft .13S and disposed to turn theE spokes as they arexpi-esentedto itby therevolving head t. Thel cutter 'head is pro-V The chuck 7 is providedwvith :projections 7 and a hook 26 is secured to the base to engage and check the same and stop the rotation in the yright position to receive the tapered end of the spoke billet when it reachesV the checking position, at which time the spoke is clutchedl by the release of the tail' spindle andthe spearing of the spoke by thersaid tail spindle.

From this statement it will be observed by considering Figs. II, III andIV that the spoke billet is chucked when the chuck is in the upper left position vseen in Fig. IV. The spoke is then advanced to theV cutter and is vturned to the general shape as indicated in Figs. II and IV. It is then advanced to the tenon cutting cutter Vwhich cuts the annular groove forming the tenon, as seen in Figs. III and IV.

It will thus be seen that by the addition of the special chuck member. to the lathe referred to and the tenon cutting device, the spgke isformed complete at a single revolu- IUD tion of the lathe, ready to be put` into a Wheel. lIt is finished by the mere cutting oiin of the tenon at the right length.

This is a general type of lathe to which the invention is applicable and of course the invention is applicable to single spindle lathes, although these Would be lacking in capacity.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is: Y

l. The combination in a spoke lathe with multiple chuck spindles on a revolvinghead, of chucks comprisingtransversely opposed rollers to receive the tapered end of a spoke, a cutter with curved blades to form the body of the spoke, and a rotary cutter disposed to form. an annular groove to form the tenon of the spoke, the said last named cutter being liXed at a specific desired distance from the chucks longitudinally of the spoke and engaging and forming the tenon by cutting laterally or from the periphery toward the axis of the spoke, so as to insure that the shoulder of the spoke shall be correctly spaced from a predetermined transverse dimension of the end of the spoke engaged by the chucks, coacting as specified.

2. The combination in a spoke'lathe, of a chuck comprising transversely opposed rollers to receive the tapered end of a spoke, a cutter with curved blades to form the body or' the spoke, and a rotary cutter disposed to form an annular groove to form the tenon yof the spoke, the said last named cutter beingixed at a specific desired distance from the chuck longitudinally of the spoke and engaging and forming the tenon by cutting laterally or from the periphery toward the axis of the spoke, so Aas to insure that the shoulder of the spoke shall be correctly spaced from a predetermined tranverse dimension of the end of the spoke engaged by the chuck, coacting asspeciied.`

8. The combination in a spoke lathe, of a chuck comprising transversely opposed rollers to receive the tapered end of a spoke, a cutter with curved blades to form the body of the spoke, and a cutter disposed to form an annular groove to form the tenon of the spoke, the said last named cutter being liXed at a specilic desired distancefrom the chuck longitudinally of the spoke and Vengaging and forming the tenon by cutting laterally yor from' the periphery "toward the axis of the spoke, so as to insurepthat the shoulder of the spoke shall be correctly sp-aced from a predetermined transverse dimension of the end of the spoke engaged by the chuck, coacting as specilied.

e. The combination in a spoke lathe, of a chuck to receive the tapered end oi? a spoke as a reference, a cutter With curved blades to form the body of the spoke, and a cutter disposed to form an annular groove to form the tenen of the spoke, thesaid last named cutter being iXed at a specific desired distance from the chuck longitudinally' of .the

spoke and engaging and forming the ktenon 7" n by cutting laterally or from the periphery toi'vard the axis of the spoke, so as to insure that the shoulder of thespoke shall be correctly spaced from a predetermined trans-fv versev dimension of the end ofthe spoke engaged by the'chuck, coacting as specified. y

In Witness whereof, I have hereunto set my hand.

HENRY FLICK.
